Random Color Generator

Generate up to 20 random colors at once with HEX, RGB, and HSL displayed for each. Lock the swatches you like and reroll the rest.

Quick start: Set how many colors you want (1-20). Five is a sensible default for quick palette exploration. → Press Generate. Each swatch shows the HEX, RGB, and HSL representation underneath the color block. → Click the lock toggle on any swatch you like. Locked swatches survive the next reroll while unlocked ones change.

Why use Random Color Generator?

Lock-and-reroll flow lets you incrementally evolve a palette without losing colors you've already approved.
Three color formats (HEX, RGB, HSL) on every swatch — copy whichever your stack expects.
Up to 20 swatches per roll covers everything from a 3-color brand palette to a 16-color illustration set.
True random over the full RGB cube — useful when you want surprise rather than the curated 'aesthetic' palettes most tools push.

Common use cases

Kickstart a brand palette by rerolling until two or three colors feel right together.
Generate avatar background colors for a chat app or directory view.
Stress-test a UI's contrast handling with random foreground/background pairs.
Find unexpected color combinations that human bias would have skipped.

How Random Color Generator keeps your data private

Color generation is a Math.random() call, not a server request. We never see which colors you generated, locked, or copied — important when those colors are part of an unannounced brand or product launch where leaking the palette early would be a problem.

About Random Color Generator

Random colors are an underrated creative input. When you're stuck on a palette decision, the easiest way out of analysis paralysis is to look at unbiased random samples and ask 'do any of these surprise me?' Xevon Tools' Random Color Generator is built around that workflow. Press Generate, get up to 20 fresh swatches, lock the ones you like, and reroll the rest until you have a set that feels right. Every swatch displays its color in three formats — HEX for the web, RGB for graphics software, and HSL for designers who want to manually nudge brightness or saturation afterward. The lock-and-reroll flow is the headline feature: it converts the tool from a one-shot novelty into a real palette-building surface where you can methodically converge on a set you love. Because the random distribution is uniform across the full RGB cube (not biased toward muted 'aesthetic' colors), you'll occasionally see jarring neon greens and dirty browns alongside elegant blues. That's the point — those surprise colors are exactly the ones that human-curated palette tools never show you, and sometimes they're the spark you need. Everything runs in your browser; no upload, no signup, and no telemetry on which colors you generate, which means brand-color exploration for unannounced products is completely safe.

Frequently asked questions

This tool produces fully unrelated random swatches — no harmonic relationship. The Palette Generator picks a base color and constructs complementary, analogous, triadic, etc. relationships from it.

Locked swatches keep their color through the next Generate press. Unlocked swatches get a new random HEX. This lets you progressively pin down a palette one color at a time.

Twenty is the cap because the page layout works best up to that size. For massive sets, generate multiple batches and combine them.

HSL makes lightness and saturation tweaks intuitive — once you have a color you like, HSL tells you how to derive a slightly lighter or more muted version manually.
